Fire-Extinguish ng Apparatus, of which the.

following is e S').C.lll0&tl011.

' M invention consists, rimarily, in the com inetion with o sprin *ler system of a tank located above the sprinklers a siohon in the connection between the tsnlc our. sprinkler pipes, with a gaseous pressure for nor- Inellyholding the Water from the tool: entering the system, and an auxiliary u'oter supply, as a power pump, and on aqueduct connected to the torn, but normally turned ofl and valvular mechanism adapted ,to be made operative by the admission of water from the tank to turn on the auxiliary supsubstantially as hereinafter described.

My invention consists further in certain combinations and sub-cornbinetions to be herein-after described.

The accompanying drawing shows it tank located above the sprinkler pipes and con nected therewith by the riser P. which includes the siphon bend that termiuetes in the valve 12 for preventing overllow of the tank s turned on.

There is shown a, vent at the highest point of the siphon merited c and a drtnv-oll cock (.5. to'draw oil the sediment in the bottom of the tank.

- The riser P. is connected to the \-"elvu.lsr

mechanism A. that comprises o casing eonteining the piston V. which is joined to the valve V. by the rod in, and it partition divides the easing into two chambers. A

small pipe 1). leads from the lower point ol riser P. to beneath the piston I. in the lower chamber, end when wotcr lills the riser l. the Water will enter beneath piston V. end lilt said piston and the conneotr-ad yelvo Y2, ud admit Water from main M. into tl upper chamber of the casingend into the r l. By means of e by-puss B and suitoblo controlling valves, the writer from main. M. can be let directly into the pipes of the system by hand.

Connected to the riser P is at distributing branch 1 provided with on outonietic sprinkler' S.

The Weter is normally excluded from the riser by air pressure horn the connected l l I i l l l 1 l l l air pump 5, but when n. sprinkler opens the ,pressure is destroyed and the water in tank T. rises in the siphon and flows into riser i and the pipes of the s stcm end by its weight and pressure opens the waterway between lnain M. and riser .1. thus imitting en auxiliary water supply enter the systern under greater pressure (or supplying the opened s rinklers. A check valve o at the open enci of the siphon prevents an overflow oi the tank, as mentioned. .By this meonsn second source of water supplyis automatic-W5 ally turned on et the supply is needed.

A pipe is shown connecting the steam pump to the system for furnishing a pump supply as a third source of Water supp v, or

moment that such a when on aqueduct is not at hand the pumpsupply becomes the second source of supply, the tank, or local supply being the first, or prinnu'y source. i

i ipe .2. leads from riser P which supplies steam to the a diaphragm l). at its term sure of water in riser 1". acting through the dia'rphrugm l). forces down a gate valve and admits steam to automatically start the pump P and deliver water through the ipe 2,1 to the riser l? and to the system of spriu ler pipes. The pipe g is provided with a check valve c and the discharge pipe of pump 8 is provided with u check valve c to prevent the m ter in the main riser from entering the pumps 1" and 5-. Pump i is provided with the usual suction pipe 5.

for alarm apparatus shown connected to riser P A gage G. provided with a contact o p controls the circuit of the battery 11., and when the pi ore of writer is present in riser l. the index "loud oi gage G. closes the normally open circuit and sounds an alarm on. tho gong G that is included in the circuit.

i do not claim herein the combination with :1 siphou'iu ti lore ted shove tributing pipes, of an nuxi agencies for utilizing the siphon, as that is disclosed in the subject imitter of my patents No. 5-lS,Tl2 darted October 29th 1895, and 572,404, dated 1) eember i, 1806.

What I claim, is

.1. in on automatic sprinkler system, the combination with the supply pipe leading to the pipe 3 pump P and has moi and the prespipes, of an auxiliary supply valve arranged to be operated by pressure of Water from the pipes leading from the local supply to the dis tributing pipes.

2. The combination with a system of sprinklers of a local supply, connelstipns from Said local supply to the distributing pipes, means for introducing gaseous pressure into the distributing pipes, connections from the distributing pipes to an auxiliary s1; pply, and a valve controlling the said auxiliary supply that is arranged to be operated by pressure of water from the local supply.

3. In an automatic sprinkler system a local supply having connections to a main riser of the system, gaseous pressure in the systern, an auxiliary supply connected to the main riser, a valve controlling the auxiliary supply that is arranged to be operated by the pressure of Water from the local stpply.

A system of sprinklers, a tank located above the system, connections from said tank to said system that comprise a siphon, gasc ous pressure in the system, an auxiliary supply for said system and a valve for controlling the said auxiliary supply that adapted to be operated by pressure of water from said tank.

5. A system of sprinklers, a tank located above said sprinklers, a siphon between the tank and sprinklers, an auxiliary supply for the sprinklers that is normally turned oil", and a valve operated by the pressine of the set,

from the local supply to the distributing tank to turn on the auxiliary supply when a sprinkler is opens d.

6. A system of sprinklers, a tank located above the sprinklers, a siphon between said tank and sprinklers gaseoi's pressure normally holding the water from the said tank from entering into the ipes oi the system, an auxiliary Water su p T that is normally turned oil, and a va ve controlling the same that is adapted to be operated by the ressure from the tank to turn on the-auxi iary supply when a sprinkler opens.

. 7. A system of sprinklers, a local supply, a gaseous pressure in said system, an auxiliary supply connected to the said system that includes a power pump, and a valve for turning on the auxiliary supply by the pressure of WilllQT/Pf the local supply.

A system of automatic sprinklers, a. l a 1 iocal supply, gaseous pressure nornieliy re-.

straining the water of the local supply from entering the system, an auxiliary supply that is normally prevented from entering the systerm by a valve that is adapted to be operated to turn on the auxiliary-supply by the pressure of water from the local supply, and an alarm apparz'itus having connections to the system, and that is made operative by the 1 d harge of the gaseous pressure when a CHARLES E. B JELLJ sprinkler opens.
